Title: Ferro-electric shift registers
IPC: G11C19/00
Filed: 1959-06-05
Abstract: 867,813. Circuits employing bi-stabie ferroelectric elements. NATIONAL CASH REGISTER CO. June 5, 1959 [June 11, 1958], No. 19248/59. Class 40 (9). [Also in Groups XIX and XL (b)] In a shift register, Fig. 1, a pulse train 40 is entered at terminal 38 to parallel circuits, each containing ferro-electric (F.E.) capacitors 20, 21 and cadmium sulphide photo-conductive (P.C.) cells 32 and to a final parallel circuit containing one F.E. capacitor only and direct connection of P.C. cell 32 to point 34. Stored information is available across resistors 35. Cross-connections between the parallel circuits is made by P.C. cells 42. Information enters the register serially through P.C. cell 41 of the first stage or in parallel via P.E. cells 41 of all stages. P.C. cells 32 and 42 are illuminated in coincidence with the B and A excursions respectively of signal 40; the light sources may be electro-luminescent elements. The polarization direction switching of F.E. capacitors 20, 21 takes place according to the following rules: when the polarization directions are (i) opposed, neither is switched by any applied pulse, (ii) both upward, both are switched by a negative input, and (iii) both downward, both are switched by a positive input. In the initial conditions of the register the polarization directions in all stages are as shown in the first stage after a sufficient number of A, B reversals of pulse train 40. For entry of a binary one into the first stage P.C. cell 41 associated therewith is illuminated during an A excursion of the pulse train, thus reversing the polarization of first stage capacitor 20. At the ensuing B excursion both first stage capacitor polarizations are switched and on the following A excursion both second stage capacitor polarizations are downward and the first stage capacitor polarization is reversed. Thus the entered binary one has been shifted to the second stage and the first stage re-set to binary zero. Similarly a binary one entered into any stage by illuminating the associated P.C. cell 41 during an A excursion will be shifted along the register and appear on the last stage for take-off at terminal 43 during a B excursion. By insertion of a F.E. capacitor at 44 in the final stage and connection of a P.C. cell between the capacitor's upper terminal and point 31 of the first stage a ring counter is formed. Constructional details.-Conductors 51, resistors 60, and P.C. cells 54, 55, 56 are deposited, printed or plated on insulating and obturating base 50, Fig. 4, and terminal pairs 57, 58 receive barium titanate F.E. capacitors. P.C. cells 54 are illuminated selectively through apertures 65 obturated by shutters 67. In an alternative construction the base is a single slab of F.E. material and the conductors &c. are plated or deposited directly on it, Fig. 6 (not shown). Specification 856,960 is referred to.

Patent GB-1202811-A (GB)
Title: Improvements in or relating to the regulation of electron guns
IPC: H02H1/00
Filed: 1968-04-25
Abstract: 1,202,811. 811. Automatic control systems for electron beam furnaces. AIR REDUCTION CO. Inc. April 25, 1968 [May 3, 1967], No.19543/68. Heading G3R. [Also in Division H2] An electron beam furnace is provided with a regulated power supply which includes a protective circuit responsive to arcing in the furnace as evidenced by a rapid rise in operating current to a trigger level, the protective circuit operating firstly to reduce the current to a level sufficient to starve the arc within a period of time which is preferably within 15 milliseconds from the time the current reaches the trigger level and subsequently automatically to restore the current. As shown, an electron beam furnace 14 is supplied from a D.C. source 28 by way of a resistor 46, a series valve 16 and a transductor 122. The normal operating current, as sensed by the transductor 122, is maintained at a desired value by a control system 26 which operates in known manner to regulate the heating current supplied to the filament of the electron gun 12. The operating voltage is maintained constant by controlling the bias applied to the grid 20 of the valve 16 in dependence upon an error signal derived from a control circuit including a voltage sensing network 18, an isolating transformer 94 associated with converters 90, 98, a voltage regulator 102 which may be of the series transistor type, and a normally closed switching circuit 22. Thus in normal operating conditions both the voltage and current supplied to the furnace are controlled at desired values, but when arcing occurs the operating current rises rapidly; this condition is detected by a sensor 24 which is connected across the series resistor 46 and which produces one output for application to the switching circuit 22 and another output for application to a restart circuit 114. When the rising current reaches a predetermined trigger level the switching circuit 22 opens to render the valve 16 much less conductive, whereby, within 15 milliseconds, the current is reduced to a level sufficient to starve the arc; subsequently, and after a predetermined period, e.g. less than 10 milliseconds, a signal from the restart circuit 114 closes the switching circuit 22 and the operating current is restored. Should the arc still persist the switching circuit 22 is again opened and the cycle repeats until the arc is extinguished. Suitable arrangements, including transistors and thyristors, for the circuits 22, 24 and 114 are described with reference to Fig. 2 (not shown).

Filed: 1961-06-01
Abstract: 947,608. Broaching machines. LAPOINTE MACHINE TOOL CO. Ltd. May 25, 1962 [June 1, 1961], No. 19794/61. Heading B3L. A puller mechanism for an internal broaching machine comprises a puller body 4 surrounded by a movable spring-loaded sleeve 1 with internal toper surfaces 2 and 9. Movement of the sleeve 1 along the body 4 under the influence of spring 11 causes, by co-operation with the toper 2, a radially inward movement of puller studs 3 to engage a circumferential groove in a broach 6 to secure it to the puller. The same sleeve movement causes in co-operation with the toper 9, a radially inward movement of two diametrically positioned studs 8 which engage co-operating flats 10 on the broach so as to lock the broach in an angular direction. The broach is released from the puller by sliding the sleeve back against the spring 11. This is effected by a cam 19 actuating a roller 17 which swings a U lever 12 about its pivots on extensions 13 of the draw head 14 which effects movement of the sleeve by rollers 15 in grooves 16. Stops 21 on the machine face plate act on the levers 12 following the release of the broach to fully retract the sleeve to facilitate the insertion of another broach.
